neither seaicliing nor sweeping produced further specimens, 

 though the attempt was repeated again and again. 



Dr. T. A. Chap.max exhibited specimens of Chri^sophanus 

 p/iLvas — (1.) a 9 captured at Eeigate ; small spots and narrow 

 hind margin to fore-wing, broad copper band to hind-wing 

 running up the veins, the copper bright and ratlier pale. 

 (2.) 15 specimens reared from eggs laid by this $ , and kept at 

 a temperature of 85^ Fahr. (egg and larva), rising to 95° for 

 the pupa?. These were a little smaller than the parent. The 

 black spots were mvich enlarged, forming in some specimens 

 an antemarginal band by confluence, and much resti'icting 

 the copper area. Hind-margin broader than in the parent, but 

 still not broad. Copper of hind-wing more or less reduced, in 

 one specimen almost to four or five spots. The tails in nearly 

 all specimens were very long : the copper bright, somewhat 

 suffused basally, but in only two or three was it suffused on 

 the apical half of the wing. The dark costal shade almost 

 wanting in the parent was marked, and to the series of three 

 most apical spots two more were added between the more 

 costal veins ; of these the parent had no trace. All the spots 

 were in most specimens very well defined — three specimens 

 whose pupffi were kept very damp are not distinguishable from 

 the others whose pupje were kept very dry. The exhibit also 

 included (3.) three specimens taken at Locarno in May 1902, 

 just after a very cold, wet spell, that affected the whole district. 

 These had the spots small ; the copper area large. One large 

 specimen (34 mm.) was reminiscent of the Lapland form 

 which Staudinger identities with the American representative 

 hf/pophlseas. (4.) Three specimens from Locarno, April 1903, 

 after ordinary weather, one of which, with the copper a 

 little reduced, might be an oidinary British sj^ecimen. The 

 other two had the spots more or less confluent, the margins of 

 the fore-wing ai-e very wide, leaving very little copper outside 

 the spots. The tails also were short and there was little 

 suffusion. (5.) 16 specimens from various parts of Spain 

 illustrating various forms of suft\ision and darkening, but 

 none perhaps typical eleiis. The darker ones differed from (2) 

 and (4) in the spots being ill- defined, surrounded by a ring of 

 less deep black (suffused), and in the black hind-margin of the
